Ethyl acetate ceev: ib qho kev tsom xam dav dav thiab nws qhov cuam tshuam zoo
Ethyl acetate (EA) yog ib qho tseem ceeb organic compound dav siv dav hauv cov kuab tshuaj, txheej, chaw tshuaj thiab cov khoom lag luam flavors. Hauv cov ntawv thov no, qhov ceev ntawm ethyl acetate yog tus tseem ceeb ntsuas uas cuam tshuam rau nws siv thiab kev ua tau zoo. Hauv tsab xov xwm no, peb yuav tham txog cov kev paub ntawm Ethyl acetate ceev thiab txheeb xyuas nws cov kev cuam tshuam kom nkag siab zoo dua thiab siv cov compound no.
Dab tsi yog Ethyl acetate ceev?
Qhov ceev ntawm ethyl acetate yog hais txog qhov loj ib feem ntim ntawm ethyl acetate ntawm qhov kub thiab siab. Feem ntau, qhov ceev ntawm ethyl acetate yog qhia nyob rau hauv grams ib cubic centimeter (g / cmlocegs ib cubic meter (kg / mp / mp / mp / mp / mp / mp / mp / mp / mp / mp / mg / mp / mg / mg / mg / mg / mg / mg / mg / mg / mg / mg / mg Raws li cov ntaub ntawv los ntawm cov qauv ntawm cov qauv, qhov ceev ntawm ethyl acetate yog kwv yees li 0.897 g / cm³. Qhov no txhais tau tias qhov loj ntawm 1 cubic centimeter ntawm ethance acetate yog kwv yees li 0.897 grams ntawm chav sov thiab siab.
Qhov tseem ceeb ntawm Kev Ua Haujlwm Saib Xyuas Kev Ncaj Ncees
Ethyl acetate ceev yog ib qho ntawm qhov tseem ceeb heev hauv kev tsim cov tshuaj lom neeg. Hauv cov ntawv thov muaj kev muaj, ceev ncaj qha cuam tshuam rau lub fluidity ntawm cov kuab tshuaj, lawv lub peev xwm los yaj, thiab kev sib xyaw ntawm kev sib xyaw. Piv txwv li, hauv cov xim ua xim, qhov ceev ntawm ethyl acetate cuam tshuam rau cov piscosity thiab theem ntawm cov xim, uas nyob rau hauv lem cuam tshuam qhov zoo ntawm cov khoom kawg. Hauv kev lag luam kws tshuaj, qhov ceev ntawm ethyl acetate tseem muaj qhov cuam tshuam loj rau solubility thiab cov tshuaj tiv thaiv hauv cov tshuaj sthtis.
Yam cuam tshuam rau qhov ntom ntawm ethyl acetate
Qhov kub: Qhov kub thiab txias: yog ib qho ntawm cov feem cuam tshuam rau qhov ceev ntawm ethyl acetate. Raws li qhov kub nce ntxiv, cov molecular placing ntawm Ethyl acetate nce, uas ua rau txo qis hauv qhov ntom ntom. Feem ntau, cov kws tsim tshuaj yuav nruj nruj ntsuas qhov kub ntawm kev sim thiab kev tsim khoom ntawm ethyl acetate yog ruaj khov nyob rau hauv ntau yam.

Purity: Lub purity ntawm Ethyl acetate kuj yog qhov tseem ceeb hauv nws qhov ntom ntom. Yog hais tias ethyl acetate muaj cov impurities, lub ntom ntawm cov ethourities yog txawv ntawm cov ethyl acetate thiab tej zaum yuav ua rau muaj kev sib xyaw ntawm cov sib xyaw kom zoo ntawm tus qauv txheem. Yog li ntawd, nws yog ib qho tseem ceeb kom ntseeg tau cov kev coj dawb huv ntawm Ethyl acetate hauv kev xyaum.

Siab: Txawm hais tias cov nyhuv ntawm lub siab ntawm cov kua yog qhov tsis tshua muaj me me, qhov ntom ntawm ethyl acetate yuav hloov me ntsis nyob rau hauv kev kub siab. Feem ntau, raws li lub siab nce, cov lwg me me ntawm cov kua yog compressed thiab ntom nce.

Npaum li cas yog qhov ceev ntawm ethyl acetate ntsuas?
Txoj kev ntsuas ntsuas qhov ceev ntawm ethyl acetate feem ntau suav nrog txoj kev nqus dej lub raj mis, cov qauv Densitometer, thiab cov raj vibrating. Ntawm lawv, cov nqus mis xaim hluav taws xob yog dav siv rau kev ntsuas kev ntsuas vim nws qhov tseeb thiab ntseeg tau. Densitometer txoj kev feem ntau yog siv ntau dua nyob rau hauv cov chaw muaj kev lag luam vim tias nws yooj yim thiab muaj peev xwm los soj ntsuam cov kev hloov ceev ceev hauv lub sijhawm. Rau cov kev xav tau siab, qhov vibrating ntawm lub raj txheej txheem kuj tseem siv tau cov kev co ntawm cov kua hauv lub raj mis kom raug ntsuas qhov ceev.

Ethyl acetate ceev yog qhov tseem ceeb heev hauv kev lag luam tshuaj, cuam tshuam rau txhua yam los ntawm kev siv cov khoom lag luam zoo kawg. Nkag siab thiab kev tswj hwm qhov ceev ntawm ethyl acetate tuaj yeem pab cov kws kho tshuaj lom neeg muaj txiaj ntsig zoo ua kom lawv cov txheej txheem ntau lawm thiab kev ruaj ntseg ntawm lawv cov khoom. Los ntawm kev txheeb xyuas qhov cuam tshuam ntawm cov yam ntxwv xws li qhov kub thiab txias, kev ua kom zoo nkauj thiab lub siab muaj peev xwm los txhim kho cov txheej txheem ntau yam kom ntseeg tau cov zis zoo.
